Share/mount ssh connection

I use SSH to connect to a remote resource just fine. I know in linux there
is a way you can mount that resource (over ssh/scp/sftp) so that it looks
like a local directory. Is there some way in Vista I can do something
similar? The server doesn't have Samba (or something similar) installed so
I can't map a drive that way. SSH clients (PuTTY, cygwin) are fine but life
would be so much simpler for me if I was able to share/map that resource and
get Vista to see it as just another, well, shared drive.

Is something like this even possible? If so, how? Could you point me to
somewhere on the web that would give me pointers?

thnx,
Christoph
